SHINGLE -MACHINE Specification of Letters Patent.

Patented April 21, 1908.

To all whom it may concern:

Be it known that I, GEORGE W. DORMAN, a citizen of the United States,residing at Everett, in the county. of Snohomish and State of'ashington, have invented a new and useful Shingle-Machine, of which thefollowing is a specification.

The invention relatesto improvements i shingle machines.

The object of the present invention is to improve the construction ofshingle machines, and to provide a sim le, inexpensive and eilicientmachine capab e of automatically feeding a shingle block to the saw, andof cutting the shingles with the tips and the butts alternately at thetop and bottom of.

the block.

'A further object of the invention is to provide a machine of thischaracter, which, when there is a knot, or other im ei'l'ection in ashingle block, nearer to one en( than the other of the same, will becapable of cutting the shingles so that the knot or other iin perfectionwill continuously occur at the tip or thin end.

With these and other objects in view, the invention consists in thecon-struction and novel combination lof, parts hereinafter fullydescribed, illustrated in the accompanying drawings, and ointed out inthe claims hereto apqpende it being understood that various c anges inthe form, proportion, size and minor details of construction, within thescope of the claims may be resorted to Without departinr from the spiritor 'sacrificing an of the advantages of the invention.

Fi 3 is an endelevation on t e same scale as Fig. 2. Fig. 4 is a pers ective view 'ofone end of the machine, il ustrating the arrangement of the feedmechanism. Fig. 5 is a side elevation partly in section of the eccentricdevice for setting or reversing the feed mechanism. Fig. 6 is an endview of the eccentric device partly in section. Fig. 7 is a -detailperspective view of the` eccentric device, thel means for actuating thesame, and the means'for throwing the eccentricdevice out of operation.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

the base of the mainframe, desi ned to be inade of metal, and whichni'ay be o any preferred construction to secure the desired strength andWeight. The .main frame is provided with an upwardly extendinvsubstantially rectangular portion2, and it 1s provided at the top andbottom thereof with longitudinal guides or ways 3 and 4, preferablyconsisting of projecting flanges and receiving a reciprocatory carriage5. The carriage 5, which is provided with the means hereinafterdescribed for clam ing a shingle block, is movable toward and circular sw 6. The bottom of the carriage is provider at its ends with integralcasings 7 in which are mounted grooved rollers or wheels 8, and thelatter run upon the flange of the bottom guide or way 4, which formsatrack for the carriage. The top of the carria-ge is provided with alongitudinal groove 9 to receive the flange of the upper guide or way 3.end nearer the saw, isconnected by a suitable pivot 10 with one end of aconnecting rod or ar 11, which extends to the upper end of anoscillatory -lever 12, and which is connected with the same by asuitable pivot 13. The ends of the connecting rod or bar maybe securedto the carriage and to the oscillatory lever in any lesired manner. Thesaid lever is fulcrumed\at its lower end on a suitable pivot 14.

The oscillatory lever is actuated by an eccentricallyarranged pivot orwrist pin 15, mounted on an arm of a gear wheel 16 and forming a crankelement. The eccentrically arranged pin or pivot 15 passes through asuitable opening of a slide 17, consisting of a block and movablelongitudinally of the oscillatorylever 12. The slide 17 which may beconstructed in any desired manneigis provided with a suitable opening toreceive the oscillator lever, and it slidably connects the same wit thegear wheel 16.

The gear Wheel 16, which is keyed or other- 1 designates `wise securedto a shaft 18, meshes with a Oma'.

The inner end of the carriage, or the and to be provided with means forLlo ' {.ardmovement of the upper shingle block rection.

the saw arbor or shaft to the gearing, which oscillates the lever 12,and the latter actuates the carriage and the means hereinafter describedfor feeding the shingle block.

The shingle block is yieldably clamped between up er and lower rolls 26and 27, pro-- vided wit spur teeth arranged at intervals, as shown, andadapted to grip the upper and lower faces of the shingle block. The spurteeth, which are arranged in annular series, project beyond the bodyportion of the rolls. 1 he lower roll 27 is journaled in suitablebearings of. the reciprocatory carriage at the bottom thereof, and theupper roll 26 is mounted in suitable bearings of a hinged clamping frameor member 28, which is provided at its ends with arms 29. Theparms 29are provided with suitable eyes or openings for the reception of a chorizontal pivot or pintle rod 30, which is adjustably mounted on thecarriage, the latter being provided with a plurality of ears or bearings3l for the reception ofthe said rod 30. The hinged frameor member 28 isadapted to swing upwardly and downwardly to engage and release a shingleblock, and it is connected by a link 32 with a weighted lever 33, whichyieldably maintains the roll 26 of the movable clam frame or member 28in engage mentzwit i the shingle block. The downengaging roll is limitedby a keeper 33a, monnted at the tbp of the carriage and re- ;'c'e'ivingthe weighted arm of the lever The lever 33, which is fulcrumed atanintermediate point by a bolt 34, or other suitable i fastening.device, is provided at one of its arms with a weight 35, and its otherarin is angularly bent and is connected by a rod 36 with afoot lever ortreadle 37 The weighted i leveriSS is located above the hinged frame ormember 28, and when the foot lever or treadle 37 is' depressed, theweighted arm of the' lever 33 and the hinged traine or member areraised. vThe weight is adapted to carry the upper engaging roll' 26automatically into enga-gement with the shingle block, when the foot isremoved from the lever or treadle 37. The foot lever or treadle 37,which ent-endsI longitudinally of the machine,

` isvfulcrumed at its inner end on the saw,=and 'ng-rod 36 is secured atits lower end to the lever or treadle 37y at a ends thereof.

The up er and lower rolls are reversely rofed the shingle blockforwardly or point between the roll -being moved forwardly or outwardly,.and the to portions of the-lower feed roll 27 beinglsi-mu taneouslymoved in the same di- The upper and lower feed rolls 26 and 27 areprovided -with ratchet wheels 38 `and 39, havingvtheir teeth shoulderedin opposite directions. The upper ratchet wheel 38 is engaged by anadjustable pawl or dog 40 of a bar or member 4l, pivotally connected atits inner or rear end 42 with an upwardly extending arm of an upper bellcrank lever dei. The outer'end of the bar or inember Ll1 is providedwith an enlargement. or head 48 provided with a terminal pivot eilt),receiying an antiffriction rbller or wheel 50. When the arm 4S is swungupward by the means hereinafter desci'ibed,`tlie bar or member 41 willbe moved inwardly oi'rearwardly, and the ratchet wheel 3S will berotated in a direction to feed the shingle block fornnrdly oi'outwardly. After the bell crank lever has been oscillated to feed theupper rolls 26, it is automatically returned toits initial position by'aspring 51, when it is free to return. The` sprin 51 is coiled atA theinner portion of the pivot 47 and its terminals are connected'respectively with the bell crank lever and with a bracket 52 from whichthe pivot 47 extends. bolted to thc carriage 5, is provided with a)rejecting arm 53 having a threaded opening tor the reception of avertically adjustable screw 54, which is adapted to support ahorizontally extending arm 48. The screw provides means, for adjustablysupporting the arm 48, and it thereby limits the return movement of theupper bell crank lever and 4controls the feeding movement.

The lower feed roll 27 is actuated in its feeding movement by means ofan adjustable pawl or dog 55, mounted in a slot or opening of a head orenlargement 56 of a bar or member 57. The head or enlargement 56 isbifurcated at the bottom to straddle the lower ratchet wheel 39, and theinner or rear end of the bar or member 57 is pivoted to the lower end ofa depending arm 58 of a bell crank le-Y ver 59, fulcrumed at its angleon a pivot 60 ofa bracket 6l, which is bolted to the 'reciprocatorycarriage at a bracket 52. The bel crank lever 59, which isactuated -inits return movement by a spring 62, is provided with a substantiallyhorizontal arm 63, having a terminal pivot, which receives ananti-friction roller or wheel 64. The lower bell crank lever isconstructed similar to the upper bell crank lever, the only differencebeing in the arrangement ofthe armshwhereby the barsor members 41 and 57will be reverselyfactuated to secure the The bracket 52, which issecurely oint below the upper y proper rotary, movement of the rolls 26and 27 to feed .the shingleblock." Theapproxi' mately vertical a'rm 43of the upper b/ell erank vlever is moved inwardly or backwardly toactuate the upper feed roll, and .the a proximately vertical arm 58 o'fthe lowerlbell crank lever is moved forwardly or outwardly to rotate thelower roll 27. The bracket 61 is provided with a horizontally rojectinarm 65, which has 'a threaded perfbration or the rece tion of averticall.v adjustable screw 66. he screw 66 adjustably supportsthe arm65 of the lower bell crank lever and composes the feeding movenient ofthe lower roll.

The bell crank levers are automaticallv operated on the return movementor stroke of the reciprocatory carriage by means of upper and lower arms67 and 68, disposed longitudinally of the machine in the direction ofthe movement of the reciprocatory carriage, and pivoted at their outerends 68a4 and 69 to the upwardly extending portion of the main frame andprovided at their inner ends with inclined ortions 70 and 71, located inthe path of t e approximately horizontal arms of the bell crank leversand presenting inclined up er faces for engagement with the saidanti-friction rollers or Wheels 53 and 61, and forming relatively fixedcams for actuating. the bell crank levers. The arms are connected at anintermediate point to the upper ends of a pair of lifting rods or bars 72 and 7 3, which are ap roximately vertical and' which are connected) attheir lower ends to levers 74 and 75. The levers 74 and 75 are fulcrumedat their outer ends on a horizontal pivot 76 .of the main frame of themachine, and they are provided at an intermediate point with upwardlyextending arms or )o1-tions, which are pivoted to the lower entls of thelifting rods or bars.

The u per and lower arms 67 and 68 are adjustablfy supported at thelimit of their downward movement by mea-ns of brackets 77 and 7S, havinghorizontally projecting .arms and provided at theouter ends thereof withvertically adjustable screws 79 and 80. These adjusting screws assist incontrolling the feeding movements of the upper and lower shingle blockengaging rolls. The adjusting screws of the bell crank lever and thearms are provided with jam nuts for locking the screws in theiradjustment.

-The levers 74 and 75, which swing u iwardly and downwardly, arealternately lifted by an eccentric device, consisting of a pair of disksS1. and S2 spaced apart and mounted on a stub shaft S3, and carryingeccentrically arranged lever-engaging means, which preferably consistsof anti-friction rollers or wheels S4 and 85, located res )ectivelybetween the disks S1 and 82, ant at? the inner face of the disk S2 inthe space between the same and the main frame. The anti-friction rollersS4 are arranged at diametrically opposite points, and are mounted onpins or pivots S6. The other anti-friction rollers or wheels S5 arelocated e ui-distant of the anti-friction vrollers or wheetlls Sl, andby this arrangement the lifting levers 74 and 7 5 will be alternatelyraised, when the eccentric device is rotated.

The eccentric device is rotated b v means of a push rod or bar ST,extending longitudinally of the machine and adjustably connected at itsinner end 8S to a short arm St) ol' the oscillatory lever. The outer)ortion of the ush rod or bar is provided with a hook shaped shoulder90, which is adapted to successively engage a series of pins 91,extending laterally from the outer face of the disk S1 and located atthe intervals between the antifriction rollers and wheels S4 and S5. Theouter portion of the push rod or bar S7 is slidably supported by a camslm )ed arm 92 of a shaft 93, and the eccentric tlevice is rotated onequarter of a revolution b v each outward stroke of the push rod or bar,which is adapted to move inwardly or backwardly without affecting theposition of the eccentric device. By this partial rotary movenient ofthe eccentric device, the anti-friction rollers or wheels S1 and aresucces-V sively brought to the top of the said eccentric device and are'aused to alternately lift the levers T4 and 75. When the upper arm 67is raised by the eccentric mechanism, its cani portion is positioned toincrease the feeding movement ol' the upper roll '26, which is therebypartially rotated a greater distance than the lower roll 2T. When inthis position the shingle block will be fed outward7 so that the buttolI the shingle will be cut at the top of the shingle block. vWhen thelower arm 65 is raised and the upper arm 69 lifted from the screws T9,as illustrated in Fig. of the drawings, the lower feed roll will berotated in excess of thc u )per feed roll and the butt of thc shingleblocl the eccentric device is in o )e1-ation, the shingles will he cutfrom the block with the tips and the butts alternately at the top andbottom of the block. 'lhe short arm SS), which extends upwardly from thelower end of the iscillating lever 1:?, is provided at its upper portionwith a slot 94, in which the pivot of the inner or rear end of the pushrod or bar S7 is adjustably secured. By raising and lowering the pivotof the inner or rear end of the push rod, the throw or stroke of thesame may be varied.

'hen there is a knot or other imperfection in a shingle block nearer toone end than the other, the shingles may bc continuously cut with theknot or imperfection at the tip by throwing the push rod or bar 87 outof operation, when the arms 67 and 68 are in position for feeding theshingle block to cut a shingle with the knot or other imperfection atthe tip thereof. This is effected by means of an operating lever 95,secured to the shaft i. ll'hen i lifted and maintained out lofengagement l bar.

` tion of the bra e and the pressure is kregu-l with the eccentricdevice. The `shaft 93 is jou'rnaled in suitable bearings of a bracket06, and the outward movement ofthe operating lever is limited by a stop97 of a curved guiding bar or member 9S. The bracket 96, which isprovided at its top with a horizontallydisposed approximately U-shapedportion 99, has an upwardly extending arm. 100,

which is arranged at the. outer edge of the outer portion `of the pushrod or bar to pre vent any lateral movement thereof.

The eccentric device .is held against accidental rotary movement bymeans ofa brake 101, which prevents the eccentric device from beingturned too far by the push rod or The brake consists of a curved castingpivot at its upper end 102 by the shaft 93 and carrying a brake shoe103, which engages the disks ofthe eccentric device. The brake is heldyieldablv in engagement with the eccentric device means of a coiled sring 104', interposed' between a substantial y l.- shaped arm or iece1,05, and the lower porlated byan adjusting screw 106, which controlsthe tensionof the spring.
